Several species of parasitoids associated with the fall armyworm, Spodoptera frugiperda, have been identified in Burkina Faso, among which Chelonus bifoveolatus, an egg-larval parasitoid, is the most abundant. This study was conducted in the region of Bobo-Dioulasso, Western Burkina Faso, from April 2023 to February 2024 under ambient laboratory conditions. The objective was to investigate the biological parameters of C. bifoveolatus reared on S. frugiperda on different host plants and at different periods of the year. Egg masses laid on maize, millet, and sorghum leaves were exposed daily to female parasitoids. The parameters studied included parasitism rate, cocoon formation rate, adult emergence rate, post-embryonic and cocoon development duration, sex-ratio, and lifespan. Parasitism rates varied between 48% and 80%, the pupation rate between 48.00% and 99.43% and the emergence rate between 27.60% and 84.91%. Post-embryonic development lasted between 14.18 ± 2.05 and 28.52 ± 2.87 days, while cocoon development ranged from 9.23 ± 1.18 to 21.29 ± 1.63 days. The sex ratio favoured males, with at least two males for every female. The adult lifespan ranged from 10.22 ± 3.74 to 13.34 ± 4.60 days. In general, performances did not vary much with host plants but were better during the rainy season than during the dry season. This study provides important information about C. bifoveolatus with a view to its use as a biological control agent of the fall armyworm.

This study examines the impact of climate change, defined as long-term changes in temperature and precipitation patterns due to natural and human factors, on women's employment in Burkina Faso, highlighting labour market participation and gender disparities. Using a static computable general equilibrium model calibrated with a gender-specific social accounting matrix, it evaluates two climate scenarios: a 2.4°C temperature increase and a 7.5 per cent decrease in precipitation by 2050. The results indicate that these climate shocks significantly reduce women's employment opportunities. The supply of paid labour for women may decrease by 3.9 per cent, with skilled women experiencing greater job losses than their unskilled counterparts. In rural areas, the domestic workload could increase by up to 0.28 per cent, further limiting women's labour market participation. These changes reinforce gender inequalities and contribute to a decline in real GDP. To counter these effects, investments in climate-resilient agriculture, water and energy infrastructure, and women's entrepreneurship are essential. Gender-responsive policies are needed to promote inclusive economic growth and reduce employment disparities.

Democracy faces growing threats from authoritarian ideologies, especially in terrorism-affected regions. We test whether citizen-targeted democracy-promotion intervention can bolster democratic support and resist authoritarian appeals. A randomized online experiment in Burkina Faso exposed participants to educational videos focusing on: (1) introduction of civic rights democracies offer, (2) general discussion of democracy’s advantages in combating terrorism, (3) Burkina Faso–specific discussion of democracy’s advantages in combating terrorism, (4) space exploration (placebo). Democracy-promotion videos increased democratic support. The general terrorism-advantage message produced the largest gains, whereas the country-specific message had little effect. Effects are not contingent on respondents’ proximity to attacks or direct experience. These findings highlight how democratic resilience can be strengthened in conflict-affected societies and inform future efforts to promote democracy.

Using a dynamic computable general equilibrium model that differentiates cropping activities and labour by sex and includes household home production, this study examines the effects of rainfall variability in Burkina Faso from both a macroeconomic perspective and a gender lens. The simulation of the annual rainfall pattern observed in the country over the past decade highlights its broad economic effects and confirms the greater sensitivity of female-led cropping activities. It also underscores the differential impacts on female and male workers in the labour market and within households, revealing the interactions between the non-market and market spheres of the economy when a rainfall shock occurs. Nevertheless, additional simulations suggest that promoting water management systems or more water-stress-resistant crop varieties could help mitigate the effects of rainfall variability and that targeted measures to support female farmers could effectively reduce their specific vulnerability.

Spermophagus niger L. is a well-known pest of roselle (Hibiscus sabdariffa L.) seeds in West Africa and responsible of mostly damage. This study first reported the presence of S. niger Motschulsky in kenaf (Hibiscus cannabinus L.) seeds stored. Samples of kenaf seeds collected at four locations in Burkina Faso. In the laboratory, the seeds were incubated until adults’ insects emerged. The emerged insects were first identified morphologically and their biodemographic parameters studied under controlled conditions (32°C ± 0.1, 43% ± 1 r.h.). The results showed that S. niger (Coleoptera: Chrysomelidae) was the only pest encountered on H. cannabinus seeds in storage and was able to complete its development cycle there. Over the course of its life, which lasts an average of 7 days, the female laid around 40 eggs, resulting in 24 individuals dominated by females. The embryonic and total development time were average 5 and 26 days, respectively. Spermophagus niger population doubled in 6 days, with an intrinsic rate of natural increase of 0.105. The finite rate of increase and the generation time averaged 1.11 and 31.86 days, respectively. This study pointed out for the first time that S. niger is able to evolve successfully on H. cannabinus seeds in storage conditions and therefore, could be a serious pest of this important crop. The data from this study could therefore be used as a basis for the post-harvest management of H. cannabinus seeds.

Revolutionary movements operated underground before and after national independence in many African countries. A communist party in Burkina Faso, the Parti communiste révolutionnaire voltaïque (PCRV), continued its underground political practice, despite democratic breakthrough. On the basis of long-term research engagement on popular struggle and the fight against impunity, the author used participant observation in street marches, meetings, sit-ins, and so on, and text analysis of pamphlets, declarations, and tracts to analyze how the PCRV is present in anti-imperialist struggles, while being absent in the public sphere.

The formalisation of informal security-providers has important consequences for citizenship, the rule of law, and human rights. We examine these policies in Burkina Faso, where formalisation has led to concerns about vigilante justice and ethnic targeting. Although African governments' reliance on informal security provision is well-documented, less is known about the origins of formalisation policies. To advance theory-building in this domain, this paper examines the political logic of empowering self-defence groups through the study of Burkina Faso's 2022 junta government, with comparisons to two prior regimes. We argue that formalisation is not only a mechanism for overcoming vexing security challenges, but is a tool used by leaders to build legitimacy and strengthen the regime's grip on power. In doing so, the article contributes insights into the origins of governmental policies towards self-defence groups, with implications for the study of political legitimacy, security provision and citizen–state relations.

Much of West Africa (and particularly the Sahel) may be once falling again under military government. This essay asks what, if anything, historians of Africa can contribute to an understanding of this phenomenon. I argue that writing the history and understanding the memory of military government will entail a renewed approach to political history and social theory. It will also entail confronting — just as so many citizens are currently doing — the peculiar failures of democracy in Africa's neoliberal era.

This article sheds light on the effects that the unrest created by early twentieth-century colonial wars had on the increasing power of African colonial intermediaries in the Northern Territories of the Gold Coast. By managing interpretation processes as well as developing a monopoly on the use of violence, interpreters, soldiers, clerks, and chiefs created what the officers called an ‘impenetrable hedge’. Analyzing how these different figures deployed their power, the article argues that there was historical continuity in the formation of the intermediaries and the methods employed by them between the years of the colonial wars and the later British administration. Despite their institutional role, however, precariousness remained a central facet of these agents’ experiences. The article shows that they were continually challenged at a grassroots level, and suggests that it was only through the use of coercion that they were able to maintain their position.

This study examines the impact of land tenure rights on the adoption of short- and long-term agricultural practices and the impact of these practices on the income and food insecurity for rural households in Burkina Faso. The bivariate probit model and propensity score matching are used to analyze data collected from 4,398 rural households. The results show that ownership of permanent land rights only increases the likelihood of adopting long-term agricultural practices. In addition, adoption of short-term practices increases household income and reduces food insecurity, while adoption of long-term practices only increases household income.

This study examines the factors influencing women farmers’ choice of adaptation strategies to reduce the negative impacts of climate change and the effects of these strategies on household income and food insecurity. A field survey was conducted among 426 women farmers in the Center-North region, which covers 7% of Burkina Faso territory. Descriptive statistics, a multinomial logit model, and a propensity score matching model were used to analyze the data collected. The results of the econometric analysis show that high domestic tasks, type of climate shocks experienced, membership in women’s group, and financial constraints are important determinants of adaptation decisions. Adaptation strategies are also found to have a positive impact on income and a negative impact on household food insecurity. These different findings highlight the need to prioritize flexible adaptation options to improve women farmers’ resilience to climate change, rather than generic solutions.

Recent efforts to improve attitudes toward outgroups and reduce support for extremists in violent settings report mixed results. Donors and aid organizations have spent millions of dollars to amplify the voices of moderate religious figures to counter violent extremism in West Africa, the Middle East, and South Asia. Despite this investment, we know little about whether such messaging persuades the primary recruits of violent extremist organizations: at-risk youth in fragile settings. In this paper, we consider whether pro-peace religious messaging can promote social cohesion among school-age respondents in Burkina Faso. Using a survey experiment, we find little evidence that such messages affect reported attitudes or behaviors toward religious extremism and find instead that it can have the unintended effect of increasing intolerance toward ethnic others. Our findings carry lessons about the inadvertent priming of ethnic identities that can result in a backlash effect among certain societal segments.
